Add   Domain wall induced spin-polarized flat bands in antiferromagnetic topological insulators
Authors: Petrov, Evgeny K. | Menshov, V. N. | Rusinov, Igor P. | Hoffmann, M. | Ernst, Arthur | Otrokov, Mikhail M. | Dugaev, V. K. | Menshchikova, Tatiana V. | Chulkov, Evgueni V.
Source: Physical Review B. 2021. Vol. 103, № 23. P. 235142-1-235142-9
Type: статьи в журналах
Date: 2021
Description: A flat band in fermionic system is a dispersionless single-particle state with a diverging effective mass and nearly zero group velocity. These flat bands are expected to support exotic properties in ... More
Add   Insight into the temperature evolution of electronic structure and mechanism of exchange interaction in EuS
Authors: Fedorov, Alexander V. | Poelchen, Georg | Eremeev, Sergey V. | Schulz, Susanne | Generalov, Alexander | Polley, C. | Laubschat, Clemens | Kliemt, Kristin | Kaya, M. | Krellner, Cornelius | Chulkov, Evgueni V. | Kummer, Kurt | Usachov, Dmitry Yu. | Ernst, Arthur | Vyalikh, Denis V.

Type: статьи в журналах
Date: 2021
Description: Discovered in 1962, the divalent ferromagnetic semiconductor EuS (T-C = 16.5 K, E-g = 1.65 eV) has remained constantly relevant to the engineering of novel magnetically active interfaces, heterostruct ... More
Add   Intrinsic magnetic topological insulator state induced by the Jahn-Teller effect
Authors: Petrov, Evgeny K. | Ernst, Arthur | Menshchikova, Tatiana V. | Chulkov, Evgueni V.
Source: The journal of physical chemistry letters. 2021. Vol. 12, № 37. P. 9076-9085
Type: статьи в журналах
Date: 2021
Description: The Jahn-Teller effect is a geometrical distortion which lowers the system symmetry and lifts orbital degeneracy in molecules and solids. It affects a wide range of properties, including magnetic and ... More
Add   Mn-rich MnSb2Te4: A topological insulator with magnetic gap closing at high Curie temperatures of 45-50 K
Authors: Wimmer, Stefan | Sánchez-Barriga, Jaime | Küppers, Philipp | Ney, Andreas | Schierle, Enrico | Freyse, Friedrich | Caha, Ondre | Michalička, Jan | Liebmann, Marcus | Primetzhofer, Daniel | Hoffman, Martin | Ernst, Arthur | Otrokov, Mikhail M. | Bihlmayer, Gustav | Weschke, Eugen | Lake, Bella | Chulkov, Evgueni V. | Morgenstern, Markus | Bauer, Günther | Springholz, Gunther | Rader, Oliver
